Glue spreader



FeB. 23, 1932. H. G. FRANCIS GLUE SPREADER Filed April '18, 1930 secure the supports to the bracket-flanges 24. It will be apparent that the shield 20, for a considerable portion of the circumference of the roll 12, prevents frictional contact of such roll with the body of the glue in the pan 14. Since the tendency of the roll to displace gluefrom one side of the pan to the other depends to a large extent upon the area of roll-surface in contact with the body of the glue, the presence of: the shield tends to prevent displacement of the glue by rotation of the roll. The shield 20 shouldlhe. mounted in such a position that a space is provided between it and-the bottom ofthe pan lt in order to permit the free return of 'glueunder the influence of gravity from the right-handlside of the tank to the left-hand side 7 It will be noted that by'e t-ending the shield fini thedirection opposite to that in which the-lower surface of the roll is moved the glue in the comparatively narrow passage v rotatable spreader. roll and a glue panfor between the shield and'the bottom ofthe pan is not subject-ed to any frictional contact with tlie'roll which would prevent its free fiowi toward the left. r s

Theshield 20, being supported from the frame 1O, remainsin constant position relative to ther'oll12irrespective of any vertical adjustmentof the pan 14.

The'shield 20 shaped-and mounted as above set forth is thepreferred form of theflowretardin or flow-preventingmeans, but other invention, consideredbro'adly. Thus, it is not necessary that thefiow-retarding means bea'isingIe member norlis. it essential that it beas thin 'radially of the roll as the shield 20 Further, jwhile I prefer to support the flow- Qretarding'means from the 'framerwhen the glue pan 'is-vertically adjustable, other ar rangementsfor its support are possible and where theglue pan 1S"I10t vertically ad ustable; the. flow-retarding means may be sup ported fromit. 1 v p Iclaim as my invention; Y

9. In a glue-spreading machine, the come bination of a frame, a rotatable spreader roll mounted in said frame, a glue-pan below said spreader roll, and adapted to contain a supply of glue into which said roll may dip, means for adjusting the vertical position of said pan relative'to vsaid roll, and

means for separating a portion of the im-' mersed roll-surface from contact with the body of the glue in said pan, said last-named means being supported independently of said pan whereby it may remain in fixed position relative to the roll when the pan is adjusted.

10. In a glue-spreading machine having a rotatable spreader roll and a glue-pan for containing a supply of glue into which said 7 roll dips, a shield located closely adjacent a portion of that part of thesuri'ace of the roll which is immersed in the glue, said shield extending in a direction oppositeto that in which the roll rotates from a point near the surface of the glue to near the'lowermost point of the roll surface, said shield being in i contact with said roll near said last mentioned point.

11. The invention set forth in claim 10 with the addition that the upper edge of said shield is spaced from the roll.

12. In aglue-spreading machine having'a rotatable spreader roll and a glue-pan for containing a supply of glue into which said roll dips, a shield for separating a portion of the immersed roll-surface from contact with the body of glue in the pan, said shield being supported independently of said pan.

13. In a glue-spreading machine, the combination of a frame, a glue-pan adapted to contain a supply of glue, a rotatable glue applying roll arranged to dip into said glue supply and'to elevate glue to the pointoat which it is to be applied, a member in con- V I tact with the glue-applying surface of said 7 roll for preventing the roll from moving an excess of glue toward the point of application, and means for adjusting the vertical position of said pan, said member being supported independently of said pan whereby its relation to said roll will not be changed by pan-adjustment.

In witness whereof,- I have hereunto set my I hand at Indianapolis, Indiana, this 14th day s of April, A. D. one thousand nine hundred and thirty.
